The computation of the one-point spectra, co-spectra and coherence of turbulent wind is conducted using the uniform-shear model from Mann (1994) [1]. The goal is to describe the spatial structure of stationary homogeneous turbulence under a neutral atmospheric stratification using only 3 adjustable parameters.
The present submission contains:
- The function MannTurb.m that computes the sheared spectral tensor
- The function MannCoherence that computes the wind co-coherence
- A LiveScript for the example file
- A data file GreatBeltSpectra.mat that contains the wind spectra from the Great belt bridge experiment for comparison with the computed spectra.

Any question, comment or suggestion is warmly welcomed.
